ToV all w71 om 'it 'may concern:

Bc it known that l, ANsoN B. MUNsoN, a citizen of the [.Tnited States, residing at Stockton, in the county of San Joaquin, State of California, have invented certain new and useful Improvements in Scrapers; andI do declare the following to vbe a full, clear, and exact description of the same, such 4as will enable others skilled in the art to which it 1.0 appertains to make and use-,the same, reference being had to the accompanving drawings, and to the charactersV of reference marked thereon, which form a part of this ap lication.

his invention relates to improvements in Scrapers and )articularly to wheel carried Scrapers, the ol) `produce a simple and inexpensive scraper whereby the operator rides on the scraper y2o and handles the same under all cdnditios ,without'any assistance, the bowl of which may be actuatedA in such a semi-automatic manner as to fill the bowl easily and with the least possible resistance or friction to lift the 2.5 scraper bowlwith its load to a sufficient dis=4 tance to clear the ground efficiently and when the same is filled and lifted to `tilt the same `backward to carry the dirt without waste, which tilting and lifting are accomplished in `3o a semi* automatic'manner with the driving ,power applied to the scraper and without the necessity of any manual labor whatsoever; also to produce a simple and effective means for dumping the contents of the bowl at any 3.5 desired point. These objects l accomplish by means of a wheel truck having a double tongue, one slidable within the other, a suporting frame on said truck, a scraper bowl liung on said frame, a lever and chain mech- 4o anism connected with said bowl and said sliding tongue for lifting and tilting said bowl to carry the dirt, means for locking said sliding tongue when said bowl 1s raised and tilted, a lover mechanism for dumping said ject yof `the invention being to4 raised and tilted as when it is filled. Fig. 3 is a rear elevation of the scraper. Fig. 4 isa fragmentary lview showing the sliding tongue mechanism. Fig. `5 is a top )lan view of the wheel carrying frame with t e scraper parts' notshown.' l

.Referring now more particularly 'to` the cluaracters of reference on the drawings 1 .designates the wheels of the device having a .forwardly projecting frame member 2 having a tongue 3 under which tongue 3 isslidably disposed a projected or auxiliary tongue 4" bearing against rollers 5 under thetongue 3. Inthe tongue 4 are two sockets 6 into which a pin? engages under certain circumstances as will appear, such pin 7 being pivoted on a weighted bell crank 8 fulcrumed upward from the frame `2 and having a foot tread member 9.

10'is a frame projecting upward from the frame 2, pivoted on the ,upper end of which is a bell crank 11 fromwhich-hangers 12 depend, such hangers supporting ascraper bowl 13 at a point a trifle forward of thecenter lino thereof. `From the upper end of the bell crank 11 a chain 14 extends under a sheave 15 and is'oonnected tothe inner' end of the tongue4. From the point of connection of the hangerlZ-gwith the'bowl1'3, hangers'lare pivotally connected with the frame 2.

Fulcruxned on the frame 10 is a lever 17 havin(T a projecting operating handle 1S, there Ibeing a link 19 connected between the said lever' 17 and the rear end of the bowl 13.

2O are brake shoes having a brake rod 21 operated by a foot lever 22.

In operation the scraper bowl lies normally in the positionshown in Fig. 1 and the forward motion of the device causes the said manner.v Then when it is desired to raise and tilt the bowl for transportation purposes, the operator presses the member 9 downward, which action releases the pin Ffrom the forward socket 6 and themotivepower pulls the tongue 4 forward independently .of

reached when the pin is engaged kinto the same by means of a weigl'it S on the member 8, and then theI whole device will bc again drawn forward. The operation of the tongue 4 as just described operates the chain 14 to 4cause the belly crank 11 to pull the link 12 upward which action raises and tilts the bowl 13 on its pivotal pointl a, which elebowl to be filled with earth in the usual the tongue 3 until the rear socket 6 is vation and tilting into the position shown in Fig. 2 permits it to retain its entire load during transportation.

To dump the contents of the bowl 13 the operator grasps the lever 1S and pulls it upward to the position shown by dotted lines in Fig. 2. This action pulls the lever 17 forward which causes the link 19 to tip the bowl 13 on its pivotal point b to empty it. The handle 18 is then operated to return to normal which returns the bowl to the position shown in Fig. 2 and when it is desired to fill the same again the pin 7 is released from the rear socket 6 and the tongue 4 is operated rearward independently of the device until the pin 7 engages the forward socket again, which permits the bowl 13 to return to normal position.

The hanger 16 acts as a connection to force the bowl 13 to take its load and also gives added strength to the frame 2 when the device is being pulled forward.

From the foregoing description it will be readily seen that I have produced a scraper having an easy and effective means for raising and tilting and dumping and moving its load and depositing the same and one which substantially fulfils all thedobjects ofthe invention as set forth herein. All of the foregoing is calculated to pick up and place in position for moving a greater amount of material' with less exertion than can be effected with any other scraper and with no loss of material while being moved to any distance desired.

While this specification sets forth in detail the present and preferred construction of my device still in practice, such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is z- 1. A scraper comprising a wheel mounted frame, a tongue on said frame, a bowl swung on said frame and means operatively connected with said tongue for raising and tilting said bowl, as described.

2. A scraper comprising a frame, a tongue on said frame, an auxiliary tongue slidable independently under said first named tongue, a bowl on said frame, and means connected with said sliding tongue for raising and tilt ing said bowl, as described.

3. A scraper comprising a frame, a bowl swung therefrom, and means on said frame for raising and tilting said bowl into such position as elevates'it from the ground and permits it to retain its load during transportation.

4. A scraper comprising a frame, a bowl suspended therefrom, a movable tongue under said frame and means for raising and tilting said bowl with the movement offsaid tongue, as set forth.

5. A scraper comprising a frame, a bowl suspended thereon, a bell crank on said frame, a link connecting one arm of said bell crank with said bowl and a chain on the other arm of said bell crank, adapted to operate the same?J as set forth.

6. A scraper comprising a horizontal frame, an upwardly projecting frame thereon, a dependent lever on said frame, a projecting handle on said lever, and a link connecting said lever with said bowl, as set forth.

In testimony whereof l ailix my signature in presence of two witnesses.
